20090014236 | Long fiber thermoplastic composite muffler system with integrated crash management - The present invention provides composite muffler systems formed of a long fiber thermoplastic. Long fiber thermoplastic technology allows the fibers, to maintain a length sufficient to provide structural strength at lower fiber loading. The long fiber thermoplastic material for forming composite muffler systems also provides increased impact strength and creep resistance as well as chemical and thermal resistance. Mufflers molded with long fiber thermoplastics demonstrate improved dimensional stability as compared to known short fiber based moldings. One suitable muffler structure is a multi-piece muffler assembly including at least one long fiber thermoplastic shell section. In accordance with the present invention, the long fiber thermoplastic material and moldings may also be combined with over-molding of preforms of unidirectional or woven inlays, which provide local structural performance. The use of such preforms is particularly suited to use in the manufacture of high temperature, structural articles such as bumper muffler combinations. | 01-15-2009 |
20100307863 | COMPOSITE MUFFLER SYSTEM THERMOSETABLE POLYMERS - A muffler assembly includes a housing defining at least one internal chamber. The housing is constructed from a composite material made from a thermoplastic resin and a reinforcing element. The reinforcing element is selected from a group of reinforcing materials consisting of glass fibers, aramid fibers, polyamide fibers, carbon fibers, graphite fibers, mineral fibers, ceramic fibers, carbon nanotubes, nano fillers, mineral fillers, ceramic fillers and combinations thereof. A pipe is received in the housing. The pipe includes at least one opening providing acoustic communication between an internal passage in the pipe and the chamber in the housing. An acoustic attenuating material is received in that chamber. | 12-09-2010 |
20110031654 | PROCESS FOR CURING A POROUS MUFFLER PREFORM - A process for curing a porous muffler preform defined by a plurality of glass fibers and a heat-curing thermoset or thermoplastic materials applied to the plurality of glass fibers is disclosed herein. The process includes the step of enclosing the muffler preform in a chamber. The process also includes the step of surrounding the muffler preform with steam. The process also includes the step of causing steam to enter the muffler preform from multiple directions. | 02-10-2011 |
20110031660 | METHOD OF FORMING A MUFFLER PREFORM - A method of forming a preform product includes filling a mold cavity with glass fibers. The mold cavity has an inlet end, a second end opposite the inlet end, and a longitudinal axis. Suction is applied simultaneously to the mold cavity axially from the second end, and suction is further simultaneously applied radially inwardly from a longitudinal passage within the mold cavity, thereby forming a preform product. | 02-10-2011 |
20110047768 | Apparatus And Method For Making Low Tangle Texturized Roving - A method of collecting a strand using an air stream dissipater comprises texturizing the strand with an air stream on a first side of the air stream dissipater, directing the texturized strand through the air stream dissipater and collecting the texturized strand in a container on the second side of the air stream dissipater. A system for texturizing a strand comprises a texturizer for texturizing the strand with an air stream, a container to collect and hold the texturized strand and an air stream dissipater provided between the texturizer and the container to dissipate excess air from the air stream and prevent the excess air from entering the container. | 03-03-2011 |
20140091497 | PROCESS FOR CURING A POROUS MUFFLER PREFORM - A process for curing a porous muffler preform defined by a plurality of glass fibers and a heat-curing thermoset or thermoplastic materials applied to the plurality of glass fibers is disclosed herein. The process includes the step of enclosing the muffler preform in a chamber. The process also includes the step of surrounding the muffler preform with steam. The process also includes the step of causing steam to enter the muffler preform from multiple directions. | 04-03-2014 |
